FREDERICK B. CUMPSTON, OF BLOOMING GROVE,

COTTON GIN.

Application filed January 2, 1923. Serial No. 610,291.

To all whom it may concern:

Be it known that l, FREDERICK B. CUM?- s'roN, a citizen of the United States, and resident of Blooming Grove, in the county of Navarro and State of Texas, have invented certain new and useful Improvements in Cotton Gins, of which the following is a specification.

This invention relates to cotton gins, and is an improvement over the construction illustrated and described in my pending ap plication for patent, Serial No. 501,394 filed oeptember 17, 1921.

Briefly stated an important object of this invention is to provide a cotton gin having a plurality of revolving ribs which move between the saws in a more or less staggered relation so that the cotton is effectively worked due to the alternate contact of the various ribs with the cotton.

Specifically the cotton gin constructed in accordance with this invention is especially adapted for use in reginning cotton seed and will gin cotton as well as the construction illustrated in my prior application, but not as rapidly.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure l is a vertical sectional view through the gin, the view illustrating the arrangement of the several ribs.

Figure 2 is a section taken on line 22 of Figure 1.

Figure 3 is an end elevation of a revolving rib.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 10 generally designates the improved cotton gin which is supplied with cotton by means of a chute 11. Attention is directed to the fact that the cotton may be fed either to the gin breast 12 by means of an opening 13 or the cotton may be fed to the huller breast 14 where it is engaged by the usual picker roll 16.

Figure 1 illustrates that the picker roll 16 engages the cotton with a plurality of saws 17 and the engagement of the cotton with the saws forces the cotton through a plurality of spaced huller ribs 19 and when the cotton passes through the huller ribs it is engaged by a series of rotating ribs 20 which move between the spaced saws in the manner illustrated in Fig. 2.

The cotton or lint is now caused to move through a plurality of stationary ribs 24 and is engaged by the usual lint removing brush 25.

Fig. 2 illustrates that the revolving blade 20 moves between the saws 17 in a more or less staggered relation so that when one rib is positioned between parallel saws the adjacent ribs will be positioned beyond the saws and consequently in their inoperative positions.

That is to say the revolving ribs on the shaft 28 alternately move between the saws and consequently the cotton is turned over in the gin breast so that the ginning operation is effectively performed.

As previously stated the use of the alternate ribs does satisfactory Work in reginning cotton seed in a high expeditious manner. However, the cotton may be originally ginned as well as in the construction illuspfrated in the prior application, but not as ast.

The cotton may be fed by way of the chute either through the opening 13 or through the opening 135. When the cotton is fed through the opening 135, the picker roll 16 will contact with the cotton and carry it through the huller ribs 19 and into the gin breast 12. Of course when the cotton enters the gin breast 12 it is subject to the action of the ribs 20 and it is then passed through the spaced members 24.

In summarizing it will be seen that three ribs 20 operate in the same plane and cooperate in an eflicient manner with the several saws 17 in efficiently detaching cotton fiber from the seeds. By the alternate arrangement of the arms 20 between the several sets of saws the cotton is turned over in the gin breast so that a large part of'the cotton fiber is stripped from the seeds Without cutting the cotton into short lengths.

Having thus described the invention, what is claimed is 1. In a cotton gin, the combination of a plurality of spaced saws, and a plurality of staggered ribs movable between the saws.

2. In a cotton gin, the combination of a plurality of spaced parallel saws, a plurality of rotary ribs mov in staggered relation, ing the ribs.

8. The combination of a plurality of a plurality of series of re- 5 spaced gin saws,

volving ribs movable staggered relation, and

messes able between the saws ity of gin saws, of series of ribs movable 10 and a shaft supportbetween the saws iii staggered relation.

5. In a gin, the combination of a plurality of gin saws, of series of ribs movable between the saws in staggered relation, the ribs of each series being movable in the same 15 plane. 7

between said saws in statlonary ribs arranged between the saws.

4:. In a gin, the combination of a plural- FREDERIGK B. CUMPSTON.
